Answer:
(a) x = -2y
(c) 3x - 2y = 0
Step-by-step explanation:
You can tell if an equation is a direct variation equation if it can be written in the format y = kx.
Note that there is no addition and subtraction in this equation.
Let's put these equations in the form y = kx.
(a) x = -2y
y = x/-2 → y = -1/2x This is equivalent to multiplying x by -1/2, so this is an example of direct variation.(b) x + 2y = 12
2y = 12 - x y = 6 - 1/2x This is not in the form y = kx since we are adding 6 to -1/2x. Therefore, this is NOT an example of direct variation.(c) 3x - 2y = 0
-2y = -3x y = 3/2x This follows the format of y = kx, so it is an example of direct variation.(d) 5x² + y = 0
y = -5x²This is not in the form of y = kx, so it is NOT an example of direct variation.(e) y = 0.3x + 1.6
1.6 is being added to 0.3x, so it is NOT an example of direct variation.(f) y - 2 = x
y = x + 2 2 is being added to x, so it is NOT an example of direct variation.The following equations are examples of direct variation:
x = -2y 3x - 2y = 0Answer:
(a) x = -2y
(c) 3x - 2y = 0
Step-by-step explanation:
You can tell if an equation is a direct variation equation if it can be written in the format y = kx.
Note that there is no addition and subtraction in this equation.
Let's put these equations in the form y = kx.
(a) x = -2y
y = x/-2 → y = -1/2x
This is equivalent to multiplying x by -1/2, so this is an example of direct variation.
(b) x + 2y = 12
2y = 12 - x
y = 6 - 1/2x
This is not in the form y = kx since we are adding 6 to -1/2x. Therefore, this is NOT an example of direct variation.
(c) 3x - 2y = 0
-2y = -3x
y = 3/2x
This follows the format of y = kx, so it is an example of direct variation.
(d) 5x² + y = 0
y = -5x²
This is not in the form of y = kx, so it is NOT an example of direct variation.
(e) y = 0.3x + 1.6
1.6 is being added to 0.3x, so it is NOT an example of direct variation.
(f) y - 2 = x
y = x + 2
2 is being added to x, so it is NOT an example of direct variation.
The following equations are examples of direct variation:
x = -2y
3x - 2y = 0

A football team carried out a report to see the impact of stretching on preventing injury. Of the 50 footballers in the squad 32 stretch regularly. Of those who stretch, 4 got injured last year. There was a total of 19 injured players last year.
The results can be presented in a frequency tree. What fraction of players who do stretch get injured?
Answer:
15 / 18
Step-by-step explanation:
19-4= 15
50-32=18
So 15/18 is fraction for injured players that didn't stretch
PLEASE MAKE SURE YOU GIVE WORKING AND AN EXPLANATION FOR YOUR ANSWER Question) The sum of the integers from -2015 to 2017 is (A) 2 (B) 2017 (C) 4033 (D) 6048
Answer: (A) 2
The sum of the integers from -2015 to 2017 = 2
Step-by-step explanation:
The sum of integers a and b is represented as a+b.
The sum of the integers from -2015 to 2017 = -2015+2017
Since -a+b=b-a
Thus, The sum of the integers from -2015 to 2017 = 2017-2015 = 2
i.e. The sum of the integers from -2015 to 2017 = 2
Thus , the correct option is (A).

Select the quadrant or axis where each ordered pair is located on the a coordinate plane
Step-by-step explanation:
Quadrant 1 is when the x axis and y axis is both positive.
Quadrant 2 is when the x axis is negative and the y value is positive.
Quadrant 3 is when the x axis and y axis is negative.
Quadrant 4 is when the x axis is positive and y value is negative.
When the point is on the x axis that means it y intercept is 0.
When the point on the y axis, it x intercept is 0.
2,4 is in quadrant 1
0,-3 is y axis

1300
B
600
Answer:
Step-by-step explanation:
tan (60)=(sin 60)/cos 60=(√3/2)/(1/2)=√3≈1.732
The value of expression tan 60° is,
⇒ tan 60° = √3
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
To find the value of expression tan 60°
Now, We can find the value of expression as;
⇒ tan 60°
⇒ sin 60° / cos 60°
⇒ (√3 / 2) / (1 / 2)
⇒ √ 3
Thus, The value of expression tan 60° is,
⇒ tan 60° = √3
